# NOTES:
|
||
# -----
|
||
#
|
||
# I Have removed inclusion of ODBM_File for OSR5
|
||
# because it core dumps and make tests fails.
|
||
#
|
||
# Support for icc compiler has been removed, because it 'breaks'
|
||
# a lot of code :-(
|
||
#
|
||
# It's *always* a good idea to first make a static link to be sure to
|
||
# have all symbols resolved with the current choice of libraries, since
|
||
# with dynamic linking, unresolved symbols are allowed an will be detected
|
||
# only at runtime (when you try to load the module or worse, when you call
|
||
# the symbol)
|
||
#
|
||
# The best choice of compiler on OSR 5 (3.2v5.*) seems to be gcc >= 2.8.0:
|
||
# -You cannot optimize with genuine sco cc (miniperl core dumps),
|
||
# so Perl is faster if compiled with gcc.
|
||
# -Even optimized for speed, gcc generated code is smaller (!!!)
|
||
# -gcc is free
|
||
# -I use ld to link which is distributed with the core OS distribution, so you
|
||
# don't need to buy the developement kit, just find someone kind enough to
|
||
# give you a binary release of gcc.
